摘 要:为揭示近27年来塔里木盆地北部景观类型格局的变化趋势,以渭-库绿洲1989、2001、2006、2011以及2016年5期的TM/ETM+为数据源,通过遥感技术及景观格局分析方法,结合野外考察数据,分析了研究区各景观格局的变化情况。结果表明:其它地类及重度盐渍化地在总体上呈减少趋势,非盐渍地则呈持续增长态势。景观的复杂性及异质性在减少。1989-2011年,渭-库绿洲斑块类型形成了很好的连接性,景观破碎度呈逐渐下降趋势,整体斑块团聚程度呈增加趋势,而2011-2016年,渭-库绿洲整体斑块团聚程度呈下降态势,斑块类型的连接性也受到破坏,景观破碎度呈上升趋势,说明研究区受人类活动的影响在加重。In order to reveal the change trend of the landscape pattern of oasis in the northern Tarim Basin during the last 27 years.Taking TM/ETM+of Ugan-Kuqa Oases in 1989,2001,2006,2011 and 2016 as the data source,the change of landscape pattern in the study area was analyzed by remote sensing technology and landscape pattern analysis method combined with field investigation data.The results showed that other types of land and severe salinization tend to decrease on the whole,and the non salinized land was on the trend of continuous growth.The complexity and heterogeneity of landscape was decreasing.In 1989-2011,the patch types of Ugan-Kuqa Oases had formed good connectivity.The fragmentation degree of landscape had been decreasing gradually,and the overall degree of aggregation was increasing.In 2011-2016,the overall degree of plaque reunion was decreasing.The connectivity of patch types was also damaged,and the fragmentation degree of landscape increased.This indicates that the influence of human activities is increasing.
